The objective of this research was to characterize the physical elements from the Córrego Santo Antônio basin, aiming to understand the influence of its surrounding areas towards the Edmundo Navarro de Andrade State Forest (ENASF). For this, we produced geomorphological and land use maps and compiled geological, soil and climatic data. Such influence was evaluated in terms of the dynamics of the transportation of the materials from the stream sources, outside of ENASF and over agricultural areas. The physical characteristic analyzes indicated that this area is sensitive to the morphogenetic processes and that they were intensified and accelerated by the land use surrounding the stream sources. Therefore, it is necessary to re-evaluate the land occupation and to fiscalize the accomplishment of the environmental laws related to the land use in valleys.
